Preheat oven to 400°F and line a large baking sheet with parchment paper.

In a medium, microwave-safe bowl, add mozzarella, almond flour, cream cheese, garlic powder, baking powder and a large pinch of salt. Microwave on high until cheeses are melted, about 1 minute. Stir in egg.

Shape dough into a ½”-thick oval on baking sheet. Dough will be sticky. Wet your hands as needed to create the oval.
